The atmosphere of the square is determined by the building of the Town Hall that has been functioning as a Town Hall since the 14th – 15th century up to the present. its present form was developed after 1597. It was continuously reconstructed until 1668. Meanwhile a gable was raised to heighten the building. On the façade of the building the first of the five paintings is the quadrilateral shaped baronial coat-of-arms of Miklós Jurisich, while in the middle there is Hungary’s historical small coat-of-arms. The third on the right is the coat-of-arms of Kőszeg, granted by Frederic III in 1446. It is still the official coat-of-arms of the town. The figural frescos among the coat-of-arms represent Hungary’s Our Lady with the child Jesus and King Stephen I, respectively. The classical gateway was made in the 19th century.
At the Town Hall, vine branches were presented to the mayor on St. George’s Day and the branches have been registered in the Book of Vine Branches since 1740. This unique book is still is use and it is kept in the local museum.
